So I have 2 offices with VoIP phones and erlite-3 routers. One office has fiber and the other has cable internet. The phones at one office have been failing because of rolling backend provider outages. Essentially routing to the VoIP service fails from one location but not the other but the internet is fine at both locations. What I want to do, as a workaround, is setup a ipsec site-to-site tunnel between the offices and then force all voip traffic from the office with the issue... to go through the office that doesnt have the issue. I can setup the tunnel no problem and I can match rules to the jive ip blocks but I'm not sure how to actually direct that traffic. Ideas?
